JOSEPH 1VI. REG-AN, OF HOLLYWOOD, CALIFORNIA.

OIL-BURNING BLACKSMITHS FORGE.

Application led May 22, 1911. Serial No. 628,844.

To all whom it may concern:

Be it known that I, JOSEPH M. REGAN, a citizen ofthe United States of America, residing at Hollywood, in the county of Los Angeles, State of California, have invented This invention relates to an oil-burning` blacksmith forge, and it may be said to consist in the provision 'of the novel features,`

and in the novel and improved construction, arrangement and combination of parts and devices therein, as will be apparent from the description and claim hereinafter.

An object of the invention is to provideA a novel and improved construction for a blacksmith forge which shall operate successfully when oil or the like is used as fuel.

Further objects of the invention are to provide an oil-burning blacksmith forge which is practical and serviceable, simple in construction, economical to use, easy to operate, and effective in action.

Other objects and the advantages of the invention will be apparent to those skilled in the art, from a consideration of the following description of the preferred form of construction in which the invention may be embodied, taken in connection with the accompanying drawings, in which- Figure 1 is a plan view of the construction of a blacksmith forge having the invention applied thereto; Fig. 2 is an enlarged central vertical section taken on the line 2 2 of Fi'g. 1; and Fig. 3 is a partly broken sectional view taken on the line 3-3 of Fig. 2. 1

' The furnace 2 4may consist of the blocks 3 `of suitable refractory material set within a suitable metal framework 4 supported by standards 5; land-it may be formed with a chamber consisting of an opening 6 in the top portion of the furnace and the passageway 7 leading from one end of the furnace to the said opening 6.

As shown, the furnace is preferablyy formed to have the upper portion of theopening 6 substantially square and to have the lower portion 8 of the rearvall of said opening curved downwardly and forwardly and meeting with the downwardly and rearwardly extending floor 9 at the bottom of the passageway 7 and opening 6; the roof 10 of the passageway 7 being straight and the side walls 1l of said passageway diverging rearwardly to said opening 6.

On the top of the furnace at the sides of the opening 6 may be disposed a number of blocks 12 of refractory material, which blocks are adapted to beadj usted in position to extend over and partly cover said' opening 6.

From the bottom of the opening 6, the passageway 13 may lead to the lower end of the furnace to permit of any molten material in the bottom portion of the opening 6 being run off to thereby clean out the furnace of such material.

The passageway 13 may be closed by means of fireclay or other suitable material 14 placed therein, and a sliding cover 15 may be arranged at the lower end of the said passageway; it being understood that in cleaning the furnace the cover 15 is moved away from the -said passageway and the fireclay poked out of the passageway by means of a suitable bar.

Liquid fuel is delivered to the passageway 7 and mixed with a suitable proportion of air by means of the device 16, or other suitable or approved liquid fuel burner, which is suitably secured to the furnace at the mouth of the passageway 7 and has connected thereto the liquid fuel supply pipe 17 and also the pipe 18 for supplying air under pressure.

The device 16 may consist of a hollow shell 19 having suitably secured thereto a rear plate 20 into which the pipe 17 is threaded to be in communication with the nozzle 21 of comparatively small diameter which nozzle is aflixed on the inner face of the plate 20 and extends substantially to the end of a converging annular portion 22 of the shell; said converging portion 22 being connected by webs 23 with a diverging portion 24 which surrounds the converging portion 22 and has therein two oppositely disposed quadrantal openings 25 for the admission of air from the atmosphere.

In operation, the liquid fuel under a pressure of about thirty-five pounds per square inch passes through the nozzle 21, and, owing to the peculiar formation of the device 16 and of the passageway 7, said liquid fuell is thoroughly mixed with the air under about four pounds pressure which is delivered by the pipe 18, as also it is mixed with the atmospheric air which is drawn through f the openings 25.

The thorough miXing of the liquid fuel with air in the right proportion and the deflection forwardly of the hot blast in consequence of its striking against the curved wall' 8 of the chamber, insures substantially perfect combustion of the liquid fuel so that any part 26 may be placed above the openling 61 and` heated to the desired degree for performing'blacksmith operations thereon.

While one form of construction in whichthe invention may be embodied has. been illustrated and particularly described, there arey various changes and modifications thereof that will readily occur to those skilled vin the art, and the right is therefore reserved to. all such .changes and modifications as do 'not depart from the spirity and scope of the invention as defined in the appended claim.

I claim: A liquid fuel burning blacksmith forge, comprising a furnace of refractory material, said furnace formed with achamberf consisting of an opening in the top portion of the furnace and a passageway having a straight roof' and rearwardly diverging sidewalls and-leading from one end of the furnace to saijdl openingthe lower portion of said opening curved downwardly and forwardly and meeting with a downwardly lname to this specification in the presence of two subscribing witnesses at Los .Angeles, county of Los Angeles, State of California, this 16th day of May, A. D. 1911.
